… (SDK-340)
- Adds 6 StandaloneLinux64 entries to set-matrix's playmode_full,
each pinned to [self-hosted, Linux, X64].
- Drops the playmode_linux output and the entire playmode-linux job
(docker + xvfb + watchdog + ci-provenance scaffolding goes away).
- Adds three Linux steps to the playmode job:
* Install Unity Hub (idempotent, apt path per
https://docs.unity.com/en-us/hub/install-hub-linux)
* Resolve Unity (linux-il2cpp module via Hub headless)
* Run PlayMode tests (mirrors the macOS step)
- Real GPU + active session means no software OpenGL, no xvfb,
no minimum-screen workaround. Cells should land in 5-10 min like
macOS / Windows.
TODO before merge:
- Capture player log (Linux) step (mirror macOS:364-380)
- Surface Unity compile errors as annotations (Linux) step
(mirror macOS:398-422)
- Confirm Hub install path /opt/unityhub/unityhub matches the apt
package layout. Adjust if .AppImage chosen instead.
- One smoke run on the runner to verify Hub install + activation +
editor install all complete cleanly.

- Linux pre-checkout step apt-installs git and git-lfs if missing. - imx-sdkbuild lacked git-lfs, so actions/checkout@v4 with lfs: true failed with exit 128: "Unable to locate executable file: git-lfs". - Idempotent: skips install when both binaries already on PATH. - Mirrors the Unity Hub install pattern; relies on passwordless sudo for the runner user.

- Removes "Ensure git and git-lfs (Linux, idempotent)" pre-checkout step. - Removes "Install Unity Hub (Linux, idempotent)" step. - Both tools now provisioned on the imx-sdkbuild Linux runner host, matching how macOS and Windows self-hosted runners are set up. - Avoids the unityhub package's interactive debconf prompt that hung cell 1 for 20 min before the runner killed it.

Summary
StandaloneLinux64into the unifiedplaymodematrix alongside Windows / macOS, pinned to[self-hosted, Linux, X64]. Drops the separateplaymode-linuxjob (the docker + xvfb + watchdog scaffolding from SDK-317 / PR ci(audience): Linux PlayMode runs under xvfb (SDK-317) #754 goes away with it, ~150 lines net).Install Unity Hub (Linux)step per Unity's Linux install guide. Skips if/opt/unityhub/unityhubalready exists, so subsequent runs cost nothing.Resolve Unity (Linux),Run PlayMode tests (Linux),Capture player log (Linux), andSurface Unity compile errors as annotations (Linux)steps modeled directly on the existing macOS pattern.Why
Unity 6 PlayMode tests on
ubuntu-latest-8-cores+ Mesa software OpenGL run ~10x slower than on Unity 2021.3 (cells take ~30 min on PR). Real GPU on a self-hosted Linux runner removes the software-rendering bottleneck; cells should land in ~5-10 min like the macOS / Windows desktop cells. SDK-340 has the underlying perf investigation.Prerequisites on the runner
sudo apt-get install).UNITY_EMAIL/UNITY_PASSWORD/UNITY_SERIALactivated once on the host so per-cell activation does not eat the seat pool, mirroring the Windows / macOS runners).Test plan
workflow_dispatchonce Hub is installed; confirm the install step short-circuits on subsequent runs.linux-il2cppmodule installs on the IL2CPP cells; build succeeds.[UnityTest]cases pass on both backends across Unity 2021.3 / 2022.3 / 6000.4.Scope
CI / runner change only. SDK code untouched.
